I'm considering using nitrous on my sr 20 so save going for a bigger laggier turbo and the fact that I wont be using that mouch power on the street.running a t518z 550's z32 maf etc.

time wise for the weight of my car my results have been ok.car weights 3375 pounds its a cefiro not an s13 or 14.making 257 rwhp ran a 13.3 with a 2.0 60' time.

just wonder what would you choose wet or dry system I have been recomended a wet system and can see the value and the reasoning behind it. hoping to use it in 3rd and 4th and a 50 shot for now will move up as needed.you thoughts appreciatedmeggala

I'd go with a wet kit, its only reliant on your fuel pump to provide more fuel, and that fuel is mixed evenly with the nitrous oxide. If cylinder one gets more nitrous than cylinder 4, it also gets more fuel. The nitrous is airborne in the intake manifold, so you run the chance of one cylinder getting more nitrous than another, and with a dry kit, that'll end up with one cylinder running too rich, and one possible running too lean.

A dry system is reliant on your injectors to get more fuel, so if they're already maxed out, I don't think you'll be able use one. I personally would go with a wet kit because I feel they are safer. I used an NX 75 shot on my old Honda and never had a problem. I ran it using a wide open throttle switch so if something went wrong, I just let off the gas and the nitrous would stop being sprayed. I also used the fuel pressure safety switch so should the pressure drop below a certain point, the nitrous would get cut off.

I'm planning on hooking my NX kit up on my SR soon, and I'll just be running a 35 shot. I'll let you know what I find.

Turbo's sound mean enough on their own. None the less, there is something even cooler about the sound of nitrous being sucked through a boosted motor. Rock on with your nitrous project!

i second the wet kit. it's a little more work to install.but worth it in the end.BTW a bigger laggier turbo is the perfect excuse for nitrous.

Wet kit is definatly the way to go if you have the money & the know how. Scaleable, controlable and safe.

Spraying on the ic is a waste of expensive nitrous. you can always run a seperate CO2 system for that.

or put a blower on the intercooler. my friend did that with his mr2. he had a fan thats turned on/off by a switch and it blows cold air onto the intercooler.
